QS9000 and ISO9001 are manufacturing standards, not quality standards. All they mean is that the manufacturer has properly documented its processes to meet the standard. They don't necessarily mean that the product being manufactured is of high quality, although any manufacturer that bothers to go through the effort and expense of being certified probably isn't making a khrap product.

Looking at the part numbers for these oil filters, they have the same basic p/n as the Purolator line. Wonder if Bosch/Purolator is involved in this brand somehow.

For instance, the P0F4006 whould fit my car that calls for the PL14006 in PureONE. I see similar p/n correlation betwween other numbers.

Filter makers will use any competitors numbering system at the request of the corporate customer requesting private labeled filters. Not always a solid assumption to assign the number system to the maker of the filter.

The old Advance Auto filters were Purolators that used Fram number system and Supertech's are Champion Lab filters with a Fram number system also.
